Do the Atlases cover both US and Canadian shorelines?
The Atlases of the connecting channels (St. Marys River; St. Lawrence River; St. Clair River, Lake St. Clair, and Detroit River; as well as the Niagara River contained in the Lake Erie edition of the Atlases) cover both US and Canadian shorelines. The lake versions (Lakes Erie, Ontario, Superior, and Huron) include only Canadian Shorelines. US lake shoreline environmental sensitivity atlases have been prepared for the United States Coast Guard (USCG) and the National Oceanic and Atmospheric Administration (NOAA) by Research Planning Incorporated (RPI).
